Abstract: The present investigation entitled impact of potassium nitrate (KNO3) and gibberellic acid (GA3) on root and shoot growth of Aonla (Emblica officinalis L.) cv. NA-4 was conducted at the Green House, Department of Horticulture, Allahabad Agricultural Institute - Deemed University, Allahabad, in 2007. Seeds were sown in polybags. Polybags were filled in with well-mixed soil, sand and farmyard manure. The ratio of soil, sand and FYM was 1:2:1, respectively. The seeds were sown 2 cm deep from. the surface. The experiment was conducted by adopting completely randomized design (CRD) with 13 treatments each replicated three times. Treatment T₉ (GA₃ 400 ppm) recorded the maximum length of root, diameter of shoot, fresh weight of shoot, fresh weight of root, dry weight of shoot and dry weight of root, thereby emerging as significantly superior to all other treatments.
